Why are we stuck on [made up] words? Jobs shall evolve alongside technology, and shall be carried out as needed to attain objectives. I've been in the IT field (mostly infra and security) for over 25 yrs, with the last ten including the public cloud, and I have witnessed solutions and JDs changing accordingly, including birth of DevOps, NetDevOps, NetSecOps, etc., etc., but in the end all that mattered was what one needed to achieve, by using what specific tools, within which boundaries one had to work, and what was to be delivered. As my first boss in IT told me, in 1995, when he promoted me as Manager Infrastructure & Security Services: "<my_name>: You could call yourself anything you want, including Vice President of Ice Cream, and I will order business cards for you as such, but here is what I expect from you in this role, and here is how much I am going to pay you, to see it done."
